A combination of commonly used pesticides can triple the risk of Parkinson's disease (PD), according to a new study released last week in the European Journal of Epidemiology. People who work and/or live near fields sprayed with paraquat, maneb and ziram are more likely to suffer from the degenerative central nervous system disorder, for which there is no cure.

Researchers note that their findings provide the first strong evidence in humans that exposure to several pesticides increases risk of PD more than exposure to individual chemicals alone.

A collection of recent studies shows that exposure to persistent organic pollutants (POPs) — including many longlasting pesticides — can slow growth rates of human embryos and shrink the genitals and weaken bones of polar bears.

My mom hackles are up. GE toxins are turning up in umbilical cordblood and the blood of pregnant women, according to a study by independent Canadian doctors. And what might be the effect of these toxins on developing fetuses? No one really knows. Let me tell you why this is big news.

All this time, Monsanto has based its assertion that crops engineered to contain the bacterial toxin, Bacillus thuringiensis (Bt), are harmless on an assumption that the toxin breaks down in the digestive system and so never enters the rest of the body. Regulators have been repeating this to us for over a generation. Now it turns out that the Bt toxin is not only surviving in our guts, but is making its way on into our bloodstreams — and if we’re pregnant, into the soon-to-be-babies in our bellies.

Healthy crops come from healthy soil. Soil fertility depends on an incredible diversity and abundance of soil critters, from the microscopic to the flying and creepy crawly. Together these critters cycle nitrogen (N) and many other essential minerals and nutrients, making them available to plants. The complexity of what goes on in healthy soil is truly awe-inspiring.

A key group of organisms that provide the soil with one nutrient that's often in short supply are the N-fixing soil bacteria. And according to a recent study by UK scientists, it turns out these organisms do a better job when they're working on organic farms.

There's good news for school children in New York. The Child Safe Playing Fields Act, which took effect May 17, prohibits use of pesticides on playgrounds, athletic fields and all grassy areas in K-12 schools across the state.

This law represents major progress toward preventing children’s exposure to pesticides and the resulting health harms. Science clearly shows that during critical developmental windows, exposure to pesticides can cause long-term and irreversible damage for children’s health and cognitive development.
